We all know that there's a lot more to MMA than Conor McGregor – but much as we pay lip service to the hidden aspects of that world, very few of us actually get to see what it looks like.

This seven-minute video documentary from Newstalk.com, produced by Luke Benson and Joseph Conroy, gives a cracking insight into the less glamorous but vitally important depths that power a global phenomenon.

Well worth those few minutes out of your lunch break.
